I was thinking about attempting to build a guitar out of spare parts of other guitars i have but this then got me thinking about future projects. Im clueless as to the electronics side of guitar construction and was wondering if anyone can suggest a good, easy to follow book that will help me out not only with the wiring and electrics but also construction and modification of guitars. Many thanks in advance
I have "Melvyn Hiscock Make Your Own Electric Guitar" and this one.

The Melvyn Hiscock book is easier to follow and has better pictures, but the Martin Koch book is loaded with much more info. I recommend you get both. You can use the Melvyn Hiscock book as a basic guide for building, and the Martin Koch book as a good reference just in case you run into something not mentioned in the other book, or want more info on something.
